  > This paper is a pre-print and has not been subject to formal peer-review. Not a great start This piece, which you present as good quality evidence, says > The lack of clear recommendations for the general public and low uptake of wearing face masks and coverings may be attributed to: (i) over-reliance on an evidence-based medicine approach and assertion that evidence was weak due to few conclusive RCT (randomised controlled trial) results in community settings, discounting high quality non-RCT evidence. Someone asks for good quality evidence and you post a link to an opinion piece saying stop over-relying on good quality evidence? I mean, your link even says they don't have much evidence > Current knowledge on the effectiveness of face masks to prevent virus transmission from COVID-19, SARS, MERS and H1N1 is mostly limited to studies of surgical masks and N95 respirators. The majority of existing studies are conducted in health care settings and focus on protection of the mask wearer as opposed to wearing a mask for the protection of others. This distinction is vital since mask wearing for the general public occurs in non-clinical situations (home, public transport, shops, restaurants) and involves both protection of oneself but also others. [...] > We emphasise that the majority of studies have been conducted in health care settings and there are therefore caveats in the ability to transfer results directly to community settings
